Basic interests of men in 62 occupations

The 22 basic interest categories on the Strong Vocational Interest Blank for Men were used to classify the interests of men in 62 occupations. The number of basic items which differentiated the interests of men in the occupation from men-in-general was divided by the total number of basic items for each category. These percentages were then ranked in descending order so that the relative importance of different types of interests for various occupations could be easily determined. At least nine categories were required to describe adequately the interests of most occupational groups.     

Self-control exertion and caffeine mouth rinsing: Effects on cycling time-trial performance

ObjectivesThe exertion of self-control has been associated with impaired performance on subsequent physical tasks also requiring self-control. However, the effect in well-trained individuals, and of nutritional intervention strategies to reduce the impact of self-control exertion are unknown. This study, therefore, explored the effect of self-control exertion on endurance performance, and pacing strategies, in well-trained individuals. A further aim was to examine the potential for a caffeine mouth rinse to attenuate any decrements in performance due to self-control exertion.MethodFollowing familiarization, fifteen trained male cyclists completed four simulated 10 km cycling time-trials on a cycle ergometer. Prior to each time-trial, participants completed a congruent Stroop task, or an incongruent Stroop task, to manipulate self-control. They also received either a caffeine (containing 40 mg of dissolved caffeine) or placebo mouth-rinse prior to, and every 2 km during, the cycling time-trial. The participants' performance time, subjective measures (perceived pain, motivation, task importance, and RPE), heart rate, and blood lactate concentration were recorded throughout the time-trials. Data were analysed using three-way (self-control*caffeine*split time) repeated measures ANOVA.ResultsThere was no effect of self-control or caffeine on overall 10 km performance time (all p > 0.05). However, following self-control exertion, split time was significantly slower at 3 km (p = 0.031) and 5 km (p = 0.034), and tended to be slower at 1 km (p = 0.088) and 7 km (p = 0.078). There was no effect of the caffeine mouth rinse, nor did this interact with self-control, to affect split times (all p > 0.05). Prior self-control exertion and a caffeine mouth rinse did not influence perceptions of pain, motivation, and task importance in well-trained individuals (all p > 0.05).ConclusionsFindings suggest that prior self-control exertion affects self-regulatory pacing strategies during the first 7 km of a 10 km cycling time-trial, in well-trained individuals. However, caffeine mouth rinsing does not attenuate the effects of self-control exertion on subsequent endurance performance.     

任务转换中惯性激活对内隐记忆的影响：来自ERPs的证据

以往研究认为内隐记忆具有不受干扰影响的自动化加工特征,其证据主要来自于对内隐记忆编码过程的研究。最近已有多项研究发现,内隐记忆受提取过程中的干扰影响,但对这一现象的产生机制目前仍尚无定论。本研究根据任务转换相关理论,通过将go/no-go范式引入干扰任务,探讨提取过程中前置干扰对内隐记忆产生影响的内在机制。结果表明,前置的干扰任务产生惯性激活时,后续的内隐记忆任务会受到影响,即启动效应降低。对惯性激活进行抑制后,随后的内隐记忆则不受影响。并且,在内隐记忆相关的N400成分上得到了与行为数据一致的结果,即在no-go干扰下,获得的N400新旧效应,在go干扰下却未被发现。研究结果证明,提取干扰对内隐记忆的影响主要由干扰任务与内隐记忆任务对认知资源的竞争导致。     

Surviving Evils and the Problem of Agency: An Essay Inspired by the Work of Claudia Card

Claudia Card did not live long enough to complete her work on surviving evils. Yet she left us an invaluable body of work on this topic. This essay surveys Card's views about the nature of evils and the ethical quandaries of surviving them. It then develops an account of survival agency that is based on Card's insights and in keeping with the agentic capacities exercised by Yezidi women and girls who have escaped from ISIS's obscene program of trafficking in women and sexual violence. Card holds that true survival requires not only staying alive and as healthy as possible but also preserving your good moral character. The essay maintains that while exercising agency to elude evil and protect yourself often depends on your own skills and personality traits, exercising agency to restore or develop your moral character often depends on social support.     

Cross-modal and intra-modal binding between identity and location in spatial working memory: The identity of objects does not help recalling their locations

In this study we tested incidental feature-to-location binding in a spatial task, both in unimodal and cross-modal conditions. In Experiment 1 we administered a computerised version of the Corsi Block-Tapping Task (CBTT) in three different conditions: the first one analogous to the original CBTT test; the second one in which locations were associated with unfamiliar images; the third one in which locations were associated with non-verbal sounds. Results showed no effect on performance by the addition of identity information. In Experiment 2, locations on the screen were associated with pitched sounds in two different conditions: one in which different pitches were randomly associated with locations and the other in which pitches were assigned to match the vertical position of the CBTT squares congruently with their frequencies. In Experiment 2 we found marginal evidence of a pitch facilitation effect in the spatial memory task. We ran a third experiment to test the same conditions of Experiment 2 with a within-subject design. Results of Experiment 3 did not confirm the pitch–location facilitation effect. We concluded that the identity of objects does not affect recalling their locations. We discuss our results within the framework of the debate about the mechanisms of “what” and “where” feature binding in working memory.     

Development and validation of the coach's task presentation scale: A quantitative self-report instrument

ObjectiveA major concern for coaches is the transmission of effective information in the moments before sport practice, when they communicate to players what they are supposed to do and how (Rink, 1994). The present study's main objective was to cover a gap in the sport psychology measurement field and to develop and validate a quantitative self-report instrument to measure the effectiveness of coaches' task presentation for athletes. The resulting instrument was the Escala de Presentación de las Tareas por Parte del Entrenador (EPTE) [Coach's Task Presentation Scale].DesignThe two studies developed to validate the EPTE used a cross-sectional research design.MethodParticipants in Study 1 included 830 college athletes aged between 18 and 27, who completed the EPTE. Participants in Study 2 included 677 college athletes aged between 17 and 29, who completed the EPTE and other questionnaires measuring coach's interpersonal style (autonomy support and controlling style) and basic psychological needs satisfaction/thwarting. Study 1 comprised translation, item formulation and examination of the reliability and factorial structure of the EPTE. Study 2 provided evidence of factorial validity and evidence of validity based on relationships with other variables in the context of the Self Determination Theory (Deci & Ryan, 2000).ResultsThe results of reliability analysis and the different sources of validity provided, demonstrated the instrument's adequacy in terms of psychometric properties.ConclusionsThe EPTE is a valid, reliable scale that can be used to measure the effectiveness of task presentation by coaches, according to the perception of athletes.     

Prior categorization can produce more efficient ordering

We hypothesized that prior categorization of an attribute might sometimes facilitate the ordering of stimuli, particularly when the number of stimuli is relatively large or some of them need to be remembered. In four experiments, participants were required to rank order either numbers or line lengths either using a selection sort or following prior categorization. The results indicated that prior categorization produced faster sorting when the number of stimuli to be ordered was relatively large and when the stimuli were not continuously visible.     

网络成瘾者的行为冲动性——来自爱荷华赌博任务的证据

以84名大学生为被试(网络成瘾和对照组被试各42名),采用感觉寻求量表和爱荷华赌博任务(Iowa Gambling Task)范式比较两组被试在感觉寻求水平和决策行为反应模式方面的差异.结果发现,与对照组被试相比,网络成瘾者的感觉寻求总分和去抑制、厌恶单调及寻求激动和惊险三个分量表得分显著增加,在IGT任务中优先选择收益和惩罚频率高的不利扑克牌,其冒险的决策策略并没有随着决策次数的增加而改变.这表明网络成瘾者的决策功能受损并表现出“即时收益优先”的决策模式和对强化物潜在风险的高耐受性.     

特里尔社会应激测试技术的介绍以及相关研究

由于能有效地诱发个体的应激反应,特里尔社会应激测试(Trier Social Stress Test,TSST)在实验室研究中受到普遍的应用。为了探测应激情境下的中央控制系统,蒙特利尔脑成像应激任务(Montreal Imaging Stress Test,MIST)对特里尔社会应激测试进行了发展和改进,为研究者提供了脑成像的研究手段。研究者基于此两种方法而进行了一系列有关应激的研究成果,在此基础上,作者提出了在中国开展实验室应激研究的可行性和初期研究方向。
